The NFL Players Association wants to determine if the Tampa Bay Buccaneers leaked information about quarterback Josh Freeman being in the NFL’s substance abuse program.

NFLPA executive director DeMaurice Smith said Tuesday, “We are sufficiently concerned about what we’ve heard to begin an investigation.”

Freeman said in a statement released by his agent late Monday that he voluntarily entered the substance-abuse program and submitted to random testing more than a year ago after mistakenly taking Ritalin instead of Adderall to treat Attention Deficit Hyperactivity Disorder.

The fifth-year pro believes someone within the Bucs organization leaked information about him being in the league’s drug testing program.

On Tuesday, Buccaneers coach Greg Schiano was asked by reporters if he was the source of the information and said, “absolutely not.”

FALCONS: Second-year offensive tackle Lamar Holmes has come to grips with one of his shortcomings -- his conditioning.

The 6-foot-6, 333-pound Holmes admitted Tuesday that he’s not in “the best of shape” to play a full game.

Through the first three games this season, Holmes had played all 191 snaps.

“Sometimes, I just get a little winded,” he said.

TITANS: Quarterback Jake Locker will miss a “few weeks” with a sprained hip, and the team says it is encouraged by the news from a second MRI exam.

VIKINGS: Coach Leslie Frazier said Tuesday that he wants to see how Christian Ponder’s injured ribs progress through the bye week before he makes a decision on who will start vs. Carolina on Oct. 13.

STEELERS: Quarterback Ben Roethlisberger hit his right hand off a defensive lineman’s hand after a touchdown pass to Jerricho Cotchery in the fourth quarter during Sunday’s 34-27 loss to Minnesota, but he didn’t expect the injury to be anything long-term.

“The doc said it was a subluxation, whatever that is,” Roethlisberger said Tuesday, as he only had tape on his right forefinger. “Yeah, it (hurt). It was kind of uncomfortable. It was pretty painful.”
